3 Claims. (Cl. 107-14) My invention relates to machines for extruding,measuring, cutting and applying edible material and to similarmechanism.

My invention relates more particularly to a machine of the typedescribed that is especially adapted for use in the making of pizza.

As is well known in the art, pizza is a food product or dish which hasbecome quite popular in the United States in the last decade, havingoriginated in Italy and adjacent southern European countries. The foodproduct is in the nature of a pie that has a thin ilat bottom crust andthe mixture that is applied to the dough and baked usually consists of alayer of tomato sauce, covered with cheese, with mushrooms, sausageslices, anchovies or any preferable food product which strikes the fancyof the producer. The dough, together with the assortment of foodproducts above mentioned, is then placed in the oven and baked untildone, and the pizza is then eaten preferably while still hot. Becausethe shape is normally round, the product is commonly known as a pizzapie.

Because of the popularity of this product, a large number of pizza pieparlors or restaurants have sprung up throughout the country, and themaking of the same in quantity has become somewhat of a mass productionproblem.

The principal object of the present invention is to provide a machinefor use in making pizza pies.

A further object of the invention is to provide a machine of the typedescribed which will extrude upon the surface of the pie dough ameasured quantity of an ingredient such as chunks of meat or sausageevenly distributed thereon and of a uniform thickness throughout. A

A further object of the invention is to provide a machine of the typedescribed that will produce the above results in a quick and expeditiousmanner so that the making of pizza pies can be greatly accelerated.

A further object of the invention is to provide a machine of the typedescribed that may be either manually operated by a single operator, ormay have power mechanism to drive the moving parts, the same :beingunder the control ,of a single operator.

For a more comprehensive understanding of the invention and themechanism which I employ in carrying out the objects of the same,reference is had to the following specification and the accompanyingdrawings upon which one embodiment thereof is illustrated.

In the drawings:

Fig. 1 is a plan view of one machine embodying my invention;

Fig. 2 is a bottom plan View thereof;

Fig, 3 is a transverse vertical sectional view thereof taken on the line3 3 of Fig. 1;

Fig. 4 is a fragmentary plan sectional view showing the cutter platethat has been moved forward in a cutting operation. v

In the embodiment of the invention which I have chosen to illustrate anddescribed the same, the construction may generally consist of a cylinderthat is fastened on a and 44. Thus when the handle 32 is rotatedin aclock- Wise direction, a piston 34 will press upon the product P baseplate or horizontal platform 12 by means of a pair l of verticallydisposed rods 14 and 16, the rods 14 and 16 being provided withcountersink heads that are fastened in countersunk openings in thebottom of the base or platform 12 and extend upwardly therefrom, beingscrewthreaded at their upper ends to receive the wing nuts 18 and 20.

The rods 14 and 16 extend upwardly through a crossbar 22 which is placeddiagonally over the top of the cylinder 10 and when the thumb nuts aretightened, the cylinder is held tightly against the ibase or platform12. The cross-bar 22 has a block 24 fastened to the bottom of the sameby a pair of screw members 26, the block 24 having an axialscrew-threaded bore 28 to receive a vertically disposed screw member 30.

I fasten an elongated handle 32 to the top end of the screw 30 andfasten a flat piston member 34 to the bottom of the screw in anon-rotatable manner.

The platform 12 may be provided with a plurality of holes or openingsr36 distributed throughout a circular area that is surrounded by the wallof the cylinder 10. I position a horizontally movable rectangularlyshaped cutter plate 38 below the bottom wall of the platform 12, thesame being held and guided for back and forth reciprocal motion by thetwo guide assemblies 40 and 42. The cutter plate 38 is also providedwith holes or openings 44 of the same diameter as the openings 36, andalso being so arranged that when the cutter plate is moved to the directequal sized passage through both the openings 36 in the cylinder 10 andwill press or extrude the food product through the aligned openings.

Means for reciprocating the cutter plate 38 may include a hand lever 46mounted at one end upon a pivot 48 fastened in the platform 12. Thehandle46 has an elongated opening 50 to receive a vertically disposedpin 52 that is fastened in the cutter Vplate 38 and projects upwardlytherefrom. When the handle 46 is moved to theleft, Fig. 1, the cutterplate 38 will thus be moved'forward a sufficient distance to cut olf therods of extruded material that have previously been pressed through thealigned openings. The forward movement of the plate 38 is controlled bya pin 39 extending downwardly from the platform 12 through an elongatedopening 41 in the cutteri plate 38.

The cutter plate 38 is reciprocated in the guides 40 and` 42 asdescribed, the guides comprising flat strips of metal that are fastenedunderneath the platform 12. The guide 40 may include a spacer strip 54the thickness ofv the f cutter plate 38, a supporting strip 56 that hasa ledge extending beneath one edge of the plate 38, and a third strip 58which also supports a cutter wire carrier 61 that is mounted below thecutter plate 38. This construction will be hereinafter described in moredetail.

The guide 42 is generally similar in construction, and

each guide assembly maybe fastened beneath the platform 12 by aplurality of screw members 60, as shown.

The platform 12 is positioned on the vertical legs 62 that extenddownwardly therefrom, and are provided with connected by a brace 74,lthe wire Wv being connected,l

between'the brackets in front of the brace 74.

In use, after extruded lengths of food product have been cut off by thecutter plate 38, ythe safety wire which is used ,Y Patented J une. 16,1959 alimitY stop for the bracket. 72, the. bracket also having, l

an upturned'l'edge or handle 80 by whichthe cutter. wire is moyed backand.forth on.the. guides 40 and 42.. Since sausage,.other meat. productsand anchoviesare usually used for makingpi'zza,` theffood products inthe cylinder are. oftenstringy and. diicult to cut off cleanly by theedges of the cutter plate openings alone, and for this reaf sonI providethe-cutter wire for movement. across the entire-bottom ofthe cylinderand cutter plate. I have found. that this producesa clean cut and thuseachpizzapieican; beremoved. andanother. piece of doughz placedin-position,

cylinder has been filledl with ground meat or other food.

which itis desired to place on the pizza pie dough. The

handle 32 is now rotated approximately one turn, the; screw 30 being,-aV comparatively large acme thread so that: theplunger or piston,34 willmove down approximately 1A inch per rotation. This action forces. orextrudes the.

edible-material from the` cylinder through theopenings in the` platform;12 and the cutter plate 38.
